Checking The Accuracy Of The Tube Voltage; Reproducibility; Measurement Set-Up - Siemens ARCADIS Avantic Maintenance Instruction

Function tests

1 Checking the accuracy of the tube voltage

The actual kV value must agree with the indicated value within the limits stated by
Siemens (max. deviation
nected to a power supply corresponding to Siemens specifications.
Tools: PTW-Nomex
Test procedure:
Refer to the information on the Nomex in the operating instructions
Connect the Nomex.
Remove the single-tank cap at the POWERPHOS after removing the two screws.
Select full image intensifier format and open the collimator fully.
Place the measuring detector on the diaphragm.
Set the following values in the operating field and check

2 Reproducibility

The coefficient of variation must not exceed 0.05 when the X-ray system is connected to a
power supply as specified by Siemens.
The technique factors should be adjusted to alternate settings and reset to the test setting
after each measurement.

2.1 Measurement set-up

Place the dosimeter in the center of the X-ray beam.
Before each new dose measurement, make sure that the indicator is reset to zero.
